Population Distribution Ecological Factors
... When hare population rises, the lynx have more food Therefore, when hares increase so do lynx!!! When lynx increase, they hunt more hares. Over time, number of hares drops And the lynx can’t eat Therefore, when the hares decrease so do the lynx!!!! When the lynx become fewer they catch less hares ...
